本文基于蔬菜主产区山东省306户菜农调研数据,运用结构方程模型验证了信息能力对菜农施药行为转变的影响。研究结果表明,信息能力潜变量对菜农施药行为转变产生显著影响且存在部分中介效应;菜农信息能力对菜农施药行为转变的直接影响主要是通过信息使用因子变量;信息能力对菜农使用农药行为转变潜变量的间接影响主要是通过信息获取因子;菜农的主观规范、知觉行为控制潜变量作为中介变量对菜农施药行为转变影响不明显;培训经历作为调节变量对菜农施药行为转变的作用路径产生一定的影响。
Based on the survey data of 306 vegetable farmers in Shandong Province, the main vegetable producing area, the paper uses the structural equation model to verify the influence of information ability on vegetable pesticide application change. The results show that the latent capacity of information ability has a significant impact on the change of pesticide application behavior and there are some intermediary effects. The direct influence of information ability of vegetable farmers on the transformation of vegetable pesticide application behavior is mainly through information use factor variables; The indirect influence of latent change is mainly through the information acquisition factor. The latent change of subjective norms and conscious control behavior of vegetable farmers as intermediary variable has no obvious effect on the change of pesticide application behavior. The role of training experience as a regulatory variable in the transformation of vegetable pesticide application behavior Have a certain impact.
